METHOD FOR LOADING WATERED RISING WELLS Russian patent published in 2009 - IPC F42D1/08 

FIELD: oil and gas production.

SUBSTANCE: invention refers to pneumatic methods of loading rising wells with hydrolabile explosive substances under conditions of underground mining. The pneumatic loading method of watered rising wells 1consists in pneumatic loading into water-proof polymer sleeve 2, diametre of which exceeds diametre of the well; sleeve 2 is fixed and maintained with stop element 3 in form of a flexible disk or flexible plates, diametre of circumscribed circle of which is bigger, than diametre of the well. Stop element 3 is strongly secured to "forelock" 4 of water-proof polymer sleeve 2. Loading hose 7 with explosive substances at its end is inserted inside water-proof polymer sleeve 2; prepared in this way assembly is delivered to a bottomhole of the well and is fixed with the stop element. Explosive substance 6 is supplied from the bottomhole of the well via the loading hose by the pneumatic method.

EFFECT: invention facilitates increased efficiency of explosive operations due to increased filling of well; also it facilitates increased power of explosion and reduced cost of loading.
